Referred compressor air compressor oil-free compressor brands, as general machinery and equipment, has been widely used in industrial and agricultural production areas. The problem is that as a motor compressor powered equipment (three-phase asynchronous motor), the failure rate is generally ranks higher than other damaged equipment motors. Why? Analysis of damage causes the compressor motor compressor motor damage for many reasons and comprehensive. We work deep into the compressor, the production site field investigation concluded that the air compressor motor damage because in addition to having in common a general failure of the motor power factor and other equipment, but also with its own particular compressor failure factor generated by the operation related . Analyzed and summarized the following main points: compressor working conditions require mechanical operation of the air compressor, electrical control is relatively simple (especially small power type) are generally stand-alone group to work independently, in a non-professional operations where the fault occurred treatment is not timely, relatively speaking, an increase in the rate of repeated failure to expand. The main fault 1, piston oil-free air compressor piston rings and packing devices are aircraft without greasing. Under normal circumstances, after essentially pure compressed gas free of oil, but because of the oil scraper ring often scraping the oil is not completely sealed good brand air compressor, resulting in often oil filler device even went on the large piston ring compressor brand so that the compressed gas oil. In addition, the exhaust gas temperature is high supply of air compressor brands, sometimes as high as 200 ℃; cooler clogged, so that the cooling effect is not good; piston ring touches the oil, are particularly vulnerable to wear and tear; beat leak valve; cylinder liner wear. 2, screw-type air compressor screw air compressor malfunction little, as long as regular maintenance of oil separator, air and oil filters, etc., will be able to ensure their normal operation.
